param-space (3 slots):
  slot 0: sma_cross.fast.length : I64

RandomSpace: 200 points, seed 0xc0ffee

best point #121 = 6.3216 pips at:
  sma_cross.fast.length = 8
  sma_cross.slow.length = 12
  exposure.scale = 1.3182

distinct total_pips across 200 points: 92

sampled ranges: sma_cross.fast.length in [2, 8] (declared [2, 8]); exposure.scale in [0.5131, 3.9784) (declared [0.5, 4.0))

OK: random continuous-range tuning produced a comparable, spread family.
